Systematic trends of 0(2)(+), 1(1)(-), 3(1)(-) and 2(1)(+) excited states in even-even nuclei

The spin and parity (J(pi)) assignments in even-even nuclei were reviewed across the nuclear chart using the Evaluated Nuclear Structure Data File (ENSDF). The prevalence of 2(1)(+) first or lowest excited states is confirmed. The properties of 0(2)(+) , 1(1)(-), and 3(1)(-) lowest excited states were reexamined using the ENSDF data evaluation procedures. The J(pi) systematic trends and correlations between level quantum numbers and nuclear physics phenomena are discussed. Published by Elsevier B.V.
